=head1 NAME

Catalyst::Action::REST::ForBrowsers - Automated REST Method Dispatching that Accommodates Browsers

=head1 SYNOPSIS

    sub foo :Local :ActionClass('REST::ForBrowsers') {
      ... do setup for HTTP method specific handlers ...
    }

    sub foo_GET : Private {
      ... do something for GET requests ...
    }

    sub foo_GET_html : Private {
      ... do something for GET requests from browsers ...
    }

    sub foo_PUT : Private {
      ... do something for PUT requests ...
    }

=head1 DESCRIPTION

This class subclasses L<Catalyst::Action::REST> to add an additional
dispatching hook. If the request is a GET request I<and> the request looks
like it comes from a browser, it tries to dispatch to a C<GET_html> method
before trying to the C<GET> method instead. All other HTTP methods are
dispatched in the same way.

For example, in the synopsis above, calling GET on "/foo" from a browser will
end up calling the C<foo_GET_html> method. If the request is I<not> from a
browser, it will call C<foo_GET>.

See L<Catalyst::Action::REST> for more details on dispatching details.

=item dispatch

This method overrides the default dispatch mechanism to the re-dispatching
mechanism described above.

=head1 SEE ALSO

You likely want to look at L<Catalyst::Controller::REST>, which implements a
sensible set of defaults for a controller doing REST.

This class automatically adds the
L<Catalyst::TraitFor::Request::REST::ForBrowsers> role to your request class.
